I think you should get rid of the "surface body" and the non-frozen solid body in DM before proceeding.
Now the next step depends on the type of interface you want between the blocks. Method 1: non-nonformal interface Proceed with the multiple independent frozen bodies. This allows you to mesh every block independently. However, you will get an interface between each block which affects your results. Method 2: conformal interface Select all the bodies, right-click and "form new part". There will be no additional interfaces created in fluent since the mesh transition between the blocks is conformal. |

I've got it, thanks so much for your quick response!
Another question is that which model should i use in FLUENT to simulate an airflow of Re= 10,000? Is there any reference materials which i can refer to to obtain information such as boundary conditions settings (intensity & viscosity ratio), solution methods, time-step sizing and etc? Thanks! Regards, Hee |

Hi everyone,
I would like to make a 3d mesh with a circular cylinder in it, but the cylinder has a finite length, so it doesn't "touch" the boundaries of the domain. I don't know how to create a mesh above and below the cylinder. Anyone has some idea about his? Thanks |

Hi darazsbence,
I know its late but just wanted to show a couple of meshing methods (for future). Even if it has finite length, you can mesh it the exact same way as mentioned above. But assuming you have another body other than the cylinder (cylinder+body) in the domain, then the basic idea for a mesh is shown in the attached pictures. Best, Rahul |

hi, can i know the step to do those meshing? when i use multizone, i got an error which is found free block in swept body. I am doing with a sphere instead of cylinder

Hi Karl,
Multizone is not a magic option that will automatically generate a hexa mesh for all geometries. Here the error is quite obvious "found free block in swept body". You need to partition your geometry using slice planes in order to help the mesher and successfully achieve the mesh you want. I would recommend you to look at tutorials on blocking strategies to gain more insights on how to partition your geometries. Have fun |
